A library of unnatural squarylated homoserine lactones (SHLs) and squarylated lactones that bear potential to modulate biofilm formation in Gram negative bacteria. At low concentrations (˜200 μM), these small molecules inhibit biofilm formation of
E. coli
. Moreover, these compounds are not toxic up to 300 μM and do not significantly attenuate
E. coli
growth. The SHLs have potential to disperse established biofilm and demonstrate an enhanced reduction (˜50%) of the maximum biofilm thickness by use of SHLs during biofilm growth.
                            一种不自然的方酰化同型半胱
氨酸内酯(SHLs)和带有潜力调节革兰氏阴性细菌
生物膜形成的方酰化内酯的图书馆。在低浓度(约200 μM)下,这些小分子抑制大肠杆菌的
生物膜形成。此外,这些化合物在300 μM以下不具有毒性,并且不会显著减弱大肠杆菌的生长。SHLs有潜力分散已建立的
生物膜,并通过在
生物膜生长过程中使用SHLs来显著减少(约50%)最大
生物膜厚度。
